Your GPU's mining hashrate. Auto-filled when you select a GPU model — override with your actual benchmark or overclocked value.
Your cost per kilowatt-hour in USD. Check your utility bill for the exact rate — it significantly impacts profitability.
Scale results for multi-GPU rigs. All revenue, costs, and efficiency metrics scale proportionally.
Enter Your Mining Setup
Select a GPU model and coin, then adjust electricity cost and pool fee to see your estimated daily profit, break-even rate, and 24-month ROI timeline.
How to Use the GPU Mining Calculator
Select Your GPU and Coin
Choose your GPU model from the dropdown — the hashrate and power consumption fields will auto-populate with benchmark data for that card. Then select the cryptocurrency you want to mine. Ravencoin (RVN) with KawPow is the default as it remains the most accessible GPU-only coin in 2026.
Enter Your Electricity Cost
Find your electricity rate on your utility bill and enter it in the electricity cost field. This is the single most important input — even small differences in electricity rate (e.g., $0.08 vs $0.12/kWh) can mean the difference between profitable and unprofitable mining. The break-even rate output tells you the maximum $/kWh at which you can still profit.
Adjust for Your Actual Setup
If you have overclocked your GPU or reduced its power limit, override the hashrate and power fields with your real-world figures. Add the number of GPUs to scale results for a multi-card rig. Expand Advanced Options to enter your hardware purchase cost for ROI and break-even calculations, and a monthly difficulty increase to model long-term profitability.
Analyze Results and Sensitivity
Review your daily, weekly, monthly, and yearly profit projections. Check the electricity sensitivity table to understand how profit changes at different energy rates. If you entered a hardware cost, the ROI timeline chart shows when your investment pays back. Export to CSV for spreadsheet analysis or use Print to save a formatted summary.
Frequently Asked Questions
Which GPU is most profitable for mining in 2026?
Profitability depends heavily on your electricity rate. In general, the RTX 4090 produces the highest absolute daily profit due to its 58 MH/s KawPow hashrate, but it also draws 320 watts and costs $1,200-$1,600 new. For efficiency-focused miners, the RTX 3070 (28 MH/s at 180W) and GTX 1660 Super (20 MH/s at 125W) offer excellent profit-per-watt ratios. AMD's RX 5700 XT and RX 6700 XT are strong performers. Use the W/MH metric to compare efficiency across cards — lower is better. At electricity rates above $0.12/kWh, only the most efficient GPUs remain profitable.
Why does my actual mining revenue differ from the calculator?
Several factors cause variance between estimated and actual results. Network difficulty changes every few blocks, and if many miners join after you start, your share of rewards decreases. Coin price fluctuates constantly — a 20% price drop directly cuts revenue by 20%. Pool luck also affects earnings; some pools have variance in block finding that smooths out over weeks. Additionally, your GPU's actual hashrate may differ from our benchmark database, especially after applying specific overclocking or undervolting profiles. We use representative 2026 average data for coin prices and network difficulty. For real-time calculations, cross-reference with WhatToMine.
What electricity rate is needed to make GPU mining profitable?
The break-even electricity rate depends on your GPU's hashrate, the coin you mine, and the current market price. Our calculator shows your maximum break-even electricity rate in the Efficiency and Metrics section. As a rough 2026 benchmark using RVN/KawPow with an RTX 3070 at typical hashrates, mining becomes marginal around $0.08-0.10/kWh and unprofitable above $0.12-0.15/kWh. GPUs with better efficiency (lower W/MH) tolerate higher electricity rates before going unprofitable. Miners with access to cheap renewable energy or subsidized industrial electricity below $0.06/kWh have a significant advantage.
How does mining pool selection affect my earnings?
Mining pool fees directly reduce your gross revenue. A 1% fee means 1% less revenue than zero-fee mining; a 2% fee means 2% less. Beyond fees, pool payout methods matter: PPLNS (Pay Per Last N Shares) pools have more variance but pay more over time, while PPS (Pay Per Share) pools offer predictable, stable payouts but typically have higher fees. Pool luck, server location (latency), and uptime also affect earnings. For KawPow coins like Ravencoin, popular pools include Mining Pool Hub, 2Miners, and Flypool. Most reputable pools charge 0.5-2% fees. Our calculator defaults to 1% — adjust this to match your chosen pool.
What is the electricity break-even rate and how do I use it?
The electricity break-even rate is the maximum cost per kilowatt-hour at which your mining setup produces zero profit — exactly covering electricity costs after pool fees. Any electricity rate above this number means you are losing money mining. For example, if your break-even rate is $0.09/kWh and your electricity costs $0.08/kWh, you are profitable by $0.01/kWh margin. This metric is especially useful when comparing electricity contracts, evaluating colocation data centers, or assessing profitability in different countries. It also tells you how much headroom you have against rising electricity prices or falling coin prices.
Should I mine directly or sell my hashrate on NiceHash?
Direct mining means you mine a specific coin and hold or sell it on an exchange. NiceHash and similar hashrate marketplaces let you sell your GPU's computing power to buyers for Bitcoin payouts, which simplifies earnings into a single currency. NiceHash typically pays slightly less than optimally-timed direct mining but offers convenience, automatic algorithm switching, and no coin exposure. The best choice depends on your goals: if you want to accumulate a specific altcoin, mine directly; if you want predictable Bitcoin payouts without coin selection complexity, NiceHash is simpler. NiceHash profitability fluctuates with demand from buyers and is not covered in this calculator's current version.
